The main issue is to have them... If you are using nonscalable fonts, the available sizes are 8,10,11, etc. Some distributions turn off scalable fonts because they tend to look ugly compared to the ones that have been tuned to a particular gridsize, but you can generally turn them on again by configuring the fontserver. E.g. I have

catalogue = /usr/X11R6/lib/X11/fonts/misc:unscaled,
        /usr/X11R6/lib/X11/fonts/75dpi:unscaled,
        /usr/X11R6/lib/X11/fonts/100dpi:unscaled,

in /etc/X11/fs/config  

and dropping the :unscaled should allow the server to generate the in-between sizes, at the expense of appearance.

Also, notice that the X11 font sizes are only relevant for postscript graphics if you are using dev.print() or dev.copy2eps(). If you use the postscript() driver directly, X11 never comes into play. (There might be a minimum legible size, though. I forget.)
